Double role of metalloporphyrins in catalytic bioinspired supramolecular metal–organic frameworks (SMOFs)

IUCrJ, 2018
Heterogeneous catalysts are of great interest in many industrial processes for environmental reasons and, during recent years, a great effort has been devoted to obtain metal–organic frameworks (MOFs) with improved catalytic behaviour. Few supramolecular

d‐Orbital Electron Spin Polarization Field Inhibits Photo‐Generated Carrier Recombination for Panel Photoelectrocatalysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A solution‐processable sub‐nanocrystal of metal coordinated conjugated reticular oligomer with spin polarization functionality is employed as an active layer in planar photoelectrochemical water splitting. The rapid recombination of photo‐generated carriers remains a critical challenge limiting the photo‐electrocatalytic water splitting performance in ...

Fluorescence Behavior of Water‐Soluble Porphyrins Immobilized on LTA Zeolite and Its Chlorogenic Acid Polyphenol Sensing in Coffee Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
During coffee bean and cherry washing, contaminants are released into water, making this process a major source of water pollution. Chlorogenic acid can be efficiently detected using hybrid zeolite–porphyrin materials by measuring fluorescence quenching, achieving detection limits lower than current regulatory thresholds.

CO2‐to‐CO Electrochemical Conversion With an Fe(I) Porphyrin Complex in Water

Angewandte Chemie, Volume 138, Issue 40, 28 September 2026.
Using in situ UV–vis/IR spectroelectrochemistry, we track CO2 reduction by a water‐soluble iron porphyrin. Rather than the usual [Fe0] intermediate in organic solvents, CO2 binds the electrogenerated [FeI] species and undergoes reductive C─O cleavage to stable [FeII‐CO]. This previously unexplored reaction pathway is facilitated by an aqueous H‐bonding
